Description

Technical Field

[0001] The utility model relates to the technical field of dust removal of protective films, in particular to an anti-static dust removal device for protective films. Background Art

[0002] Protective film is a thin film attached to the surface of an object, often used to protect the surface of an object from damage, pollution and scratches. Protective film is usually made of polymer materials, such as polyethylene, polyurethane, polypropylene, etc. These materials have good plasticity and wear resistance, and can withstand friction and impact on the surface of the object. Protective film is widely used in many fields, such as electronic products, automobiles, building materials, furniture, glass, etc. It can reduce wear and corrosion on the surface of the object and increase its service life and value.

[0003] Protective films are often used to protect product surfaces, including one type of protective film used for anti-static purposes. The anti-static ability of protective films mainly depends on the conductivity of their surface. When dust or dirt from the production process adheres to the surface of the protective film, they form an insulating layer that hinders the transfer of charge between the protective film and the surrounding environment. In this way, the protective film cannot effectively disperse or absorb static electricity, and static electricity may accumulate and release on the surface, increasing the risk of electrostatic interference.

[0004] The prior art has the following deficiencies: conventional protective film anti-static dust removal devices usually use electrostatic adsorption to adsorb dust on the surface of the protective film. Its working principle is to bring a negatively charged corona tube close to the surface of the protective film to make the dust particles carry negatively charged ions, and then adsorb the dust through the integrated electrode plate with a positive surface charge. Since the corona tube will generate heat when it is energized, if it is close to the surface of the protective film for a long time, the protective film may be easily melted and deformed by the heat, which may cause irreversible serious damage to the surface of the protective film anti-static dust removal device. Therefore, conventional protective film anti-static dust removal devices have the problem that the protective film may be deformed by heat during dust removal.

[0005] Therefore, it is necessary to invent a protective film anti-static dust removal device. Utility Model Content
